Saving power, money, and the planet

The Low Carbon Living CRC was founded to reduce carbon emissions in Australia’s built environment: from a goal of 10Mt in emissions reductions, the CRC achieved 12.8Mt in savings by 2020, and is predicted to save 100Mt by 2027. The message from its research is clear: low carbon living provides benefits far beyond emissions reductions.

The Australian Bureau of Statistics estimates that the population will rise from 25 million to 30 million by 2030, and potentially come close to 50 million by 2066. All of these people will need somewhere to live. 

Simultaneously, climate change demands that Australia rethinks the way it builds and designs infrastructure and housing to deal with increased heat, less rain, and new energy sources. 

The Low-Carbon Living CRC spent almost eight years, starting in 2012, and finishing in 2019, solving both problems simultaneously. It has helped the nation meet its international emissions reduction targets, driving new policies, building methods, and materials.

Importantly, it has driven innovation in the sector through a creative approach to problem solving.

The figures are astounding: an independent audit of the CRC’s work sees a $1.1bn economic benefit to Australia by 2021, a benefit/cost ratio of more than 9:1 from a total investment of $116m. With a founding goal of $684m in economic benefits, it has smashed its expectations.

The Low Carbon Living CRC achieved this through pilot projects on net-zero emissions housing, databases of the carbon footprint of individual building materials, and resources for home owners on the benefits of renovation vs. demolition. Broadly, the CRC’s researched focused on three key areas: integrated building systems, low-carbon precincts, and engaged communities.

Its research reverberated internationally, with a global network of partnerships, including the KTH Royal Institute of Technology, Sweden; Tongji University, China; and Concordia University, Canada.

The CRC also developed the United Nations Environment Programme (UNEP) Guidelines for Sustainable Cities and Communities and Greening Universities Toolkit, and is also the only Australian member of the Global Building and Construction Alliance.

Scientia Professor Deo Prasad AO, the CEO of the CRCLCL has highlighted the levels of measured success of this CRC including the levels of evidence created to underpin policies and design and planning within the built environment. The success of this CRC has led to a much higher level of industry engagement on innovation in the built environment.

To reduce carbon, you need a baseline measurement. The preparation and design stages are the phases with the greatest potential to influence sustainability, circularity and carbon emissions.

This is why the Low-Carbon Living CRC created the Integrated Carbon Metrics database, giving developers the carbon footprint of individual building materials. 

From there, the CRC developed its Embodied Carbon Explorer, and Precinct Carbon Assessment tools to help designers, manufacturers, planners and developers calculate embodied carbon emissions during the planning stage.

Its evidence-based policy proposals call for a shift in the building codes to would unlock energy/power bill savings for homeowners, and ensure better long-term return on investment for developers.

Reaching net-zero 
Australia, as a signatory to the Paris Agreement in 2015, is obligated to reach net-zero on emissions by the second half of the century. This means that the total amount of carbon being released into the atmosphere (through energy generation, fossil fuels, agriculture, land clearing, etc) has to be balanced out with carbon being removed from the atmosphere. According to the CRC, the construction, operation and maintenance of Australian buildings accounts for 25% of Australia’s emissions.

Net-zero homes and buildings, which do not add to Australia’s total carbon emissions, are a legal, mathematic, and economic necessity if we are to meet our goals. The Council of Australian Governments (COAG) Energy Council has a plan in place for that crucial 25% of emissions: Trajectory for Low Energy Buildings, a national plan created with the findings of the CRC.

Net-zero homes are already a reality. Relying on research from the CRC, SJD Homes built Australia’s first net-zero energy home, which uses a combination of insulation, double glazed windows, solar panels, LED lighting, draught proofing, and an optimised physical orientation to keep the house cool in summer but warm in winter.

For consumers, there is the dual benefit of lower power bills and increased comfort throughout the year. It is a clear-cut example of innovation in practice, a novel idea put into practice that the market is willing to pay for.

Importantly, it is a demonstration of what is possible with the technology of today, not some future idealisation.

 “There’s really no reason for future residential developments not to be zero-energy homes. More work is required to educate the public, the industry and governments to make this business as usual, not the current approach,” Dr Josh Byrne, Low-Carbon Living CRC. 

The Low Carbon Concrete program has also delivered new building materials which Australia can manufacture and export globally, 

including produced a patent for a geopolymer concrete with 50% less emissions than its traditional counterpart. It is now being used in a world-first geopolymer trial on a Sydney road, following trials with Sydney Water and NSW Ports.

It is helping businesses navigate a low-carbon focused economy, with research papers like Preparing your Business for the Zero-Carbon Circular Economy providing planning pathways for materials suppliers, trades and contractors; transport companies and architects, engineers and other design firms. 

Of course, replacing all of Australia’s buildings would result in a massive carbon emissions spike, which is why the CRC has resources to help homeowners and tradespeople to retrofit to existing stock. 

Building the future
The doors of the CRC have now shut, but its work has laid the foundations upon which Australia’s low-carbon housing future will be built. Business, communities, and researchers will reap the benefits in the years to come, alongside individuals living in low-carbon housing. By all measures, the CRC has had an incredible impact, saving money, power, and the planet.

In 2016 I published a blog article titled Moonshots for Australia: 7 For Now. It’s one of many I have posted on business and innovation in Australia. In that book, I highlighted a number of Industries of the Future among a number of proposed Moonshots. I self-published a book, Innovation in Australia – Creating prosperity for future generations, in 2019, with a follow-up COVID edition in 2020. There is no doubt COVID is causing massive disruption. Prior to COVID, there was little conversation about National Sovereignty or supply chains. Even now, these topics are fading, and we remain preoccupied with productivity and jobs! My motivation for this writing has been the absence of a coherent narrative for Australia’s business future. Over the past six years, little has changed. The Australian ‘psyche’ regarding our political and business systems is programmed to avoid taking a long-term perspective. The short-term nature of Government (3 to 4-year terms), the short-term horizon of the business system (driven by shareholder value), the media culture (infotainment and ‘gotcha’ games), the general Australian population’s cynical perspective and a preoccupation with a lifestyle all create a malaise of strategic thinking and conversation. Ultimately, it leads to a leadership vacuum at all levels. In recent years we have seen the leadership of some of our significant institutions failing to live up to the most basic standards, with Royal Commissions, Inquiries and investigations consuming excessive time and resources. · Catholic Church and other religious bodies · Trade Unions · Banks (and businesses generally, take casinos, for example) · the Australian Defence Force · the Australian cricket teams · our elected representatives and the staff of Parliament House As they say, “A fish rots from the head!” At best, the leadership behaviour in those institutions could be described as unethical and, at worst….just bankrupt! In the last decade, politicians have led us through a game of “leadership by musical chairs” – although, for now, it has stabilised. However, there is still an absence of a coherent narrative about business and wealth creation. It is a challenge. One attempt to provide such a narrative has been the Intergenerational Reports produced by our federal Government every few years since 2002. The shortcomings of the latest Intergenerational Report Each Intergenerational Report examines the long-term sustainability of current government policies and how demographic, technological, and other structural trends may affect the economy and the budget over the next 40 years. The fifth and most recent Intergenerational Report released in 2021 (preceded by Reports in 2002, 2007, 2010 and 2015) provides a narrative about Australia’s future – in essence, it is an extension of the status quo. The Report also highlights three key insights: 1. First, our population is growing slower and ageing faster than expected. 2. The Australian economy will continue to grow, but slower than previously thought. 3. While Australia’s debt is sustainable and low by international standards, the ageing of our population will pressure revenue and expenditure. However, its release came and went with a whimper. The recent Summit on (what was it, Jobs and Skills and productivity?) also seems to have made the difference of a ‘snowflake’ in hell in terms of identifying our long-term challenges and growth industries. Let’s look back to see how we got here and what we can learn. Australia over the last 40 years During Australia’s last period of significant economic reform (the late 1980s and early 1990s), there was a positive attempt at building an inclusive national narrative between Government and business. Multiple documents were published, including: · Australia Reconstructed (1987) – ACTU · Enterprise Bargaining a Better Way of Working (1989) – Business Council of Australia · Innovation in Australia (1991) – Boston Consulting Group · Australia 2010: Creating the Future Australia (1993) – Business Council of Australia · and others. There were workshops, consultations with industry leaders, and conferences across industries to pursue a national microeconomic reform agenda. Remember these concepts? · global competitiveness · benchmarking · best practice · award restructuring and enterprising bargaining · training, management education and multiskilling. This agenda was at the heart of the business conversation. During that time, the Government encouraged high levels of engagement with stakeholders. As a result, I worked with a small group of training professionals to contribute to the debate. Our contribution included events and publications over several years, including What Dawkins, Kelty and Howard All Agree On – Human Resources Strategies for Our Nation (published by the Australian Institute of Training and Development). Unfortunately, these long-term strategic discussions are nowhere near as prevalent among Government and industry today. The 1980s and 1990s were a time of radical change in Australia. It included: · floating the $A · deregulation · award restructuring · lowering/abolishing tariffs · Corporatisation and Commercialisation Ross Garnaut posits that the reforms enabled Australia to lead the developed world in productivity growth – given that it had spent most of the 20th century at the bottom of the developed country league table. However, in his work, The Great Reset, Garnaut says that over the next 20 years, our growth was attributable to the China mining boom, and from there, we settled into “The DOG days” – Australia moved to the back of a slow-moving pack! One unintended consequence of opening our economy to the world is the emasculation of the Australian manufacturing base. The manic pursuit of increased efficiency, lower costs, and shareholder value meant much of the labour-intensive work was outsourced. Manufacturing is now less than 6% of our GDP , less than half of what it was 30 years ago!
